TO DEVELOP A PROCESS TO REFINE ALUMINUM SCRAP, SALT COMPOSITION TO REMOVE MAGNESIUM FROM MOLTEN ALUMINUM WILL BE SELECTED. THE PROCESS SHALL HAVE ADVANTAGES IN REGARD TO ENVIRONMENTAL AND HEALTH HAZARDS OVER PRESENTLY CONSIDERED APPROACHES, AND THE SALT COMPOSITION SHALL PERMITS ITS ELECTROCHEMICAL REGENERATION ACCORDING TO A NOVEL CONCEPT. THE PHASE I EFFORT WILL FOCUS ON THE DELECTION OF PROMISING SALT COMPOSITIONS ON THE DETERMINATION OF REACTION RATES FOR THE OXIDATION OF MAGNESIUM CONTAINED IN LIQUID ALUMINUM. EXPERIMENTS WILL BE DESIGNED THAT PERMIT RATE DETERMINATIONS AT WELL-CONTROLLED MASS TRANSFER CONDITIONS AT THE LIQUID-LIQUID INTERFACE.
